Here is photo evidence of the bulge by popular demand. It is thought that this apparent out of spec ammo is causing some issues in some chambers. In the photo one can clearly see the case bulge.

The bulge is from loaded factory Hornady ammo. It can be fixed with handloads by running the brass through a shaping die.

Is this a new issue or has this always been an issue with the Hornady ammo?

I think we believe that its fairly new. Who keeps Grendel ammo and never shoots it to measure?

I've been shooting Hornady 123 gr Amax for 3 years and the 123 gr SSTs for two yeaars and I've never experienced this, as a matter of fact I've never had a ftf in my Grendel. I will however look more closely from now on when loading my mags.

Many chambers won't experience a problem ARP rifles did and where pulled and now are selling at a deep discount.

So this isn't a reload? I'll need to straight edge some to see if it is a issue with ammo I have. Never had any issues with Hornady and never put it to a straight edge either. Something to test but if mine was bulged, it didn't matter.

Yep, I have some factory SST ammo with the bulge as well.  It is not uniform.  A case may be flat on one side and bulged on the other.

Just checked 123 SST factory ammo - very slight bulge.  Not as pronounced as the top photo, but almost.

All of my Hornady made ammo is shooting pretty hot in my new build with slightly cratered primers.  100+ deg at the range I should add, so that's not helping any.

Olyimaz,

A reworked and bushed bolt with a tighter fitting firing pin may prevent those cratered primers. Try LRI or Gre'-Tan rifles. Greg is a champion at this type of work. Good luck.
